Implementation of Network Access Control (NAC) with Zero Trust Security

Network Access Control (NAC) with The Zero Trust Model

Today, when assets are constantly connecting and disconnecting from the network, the security risks they bring along with, is potentially high. Employees, clients, vendors etc. will all have different needs from corporate data of an organization and the levels of access to information will be different for all.

Managing the “n” number of resources, connections and user access could pose complex in such a scenario. When cloud-based architectures are involved, single, multiple or hybrids, the resources are likely to be scattered across numerous IT ecosystems. Ensuring that the right users have access to the right amount of right information under secured conditions can be challenging and this forms the underlying motive of the Zero Trust Security Model.

Never Trust, Always Verify is the fundamental rule followed by the Zero Trust Security approach wherein no matter who the user is, or device be, if they are a previously verified user or connected to a permissioned network, they must always be authenticated, authorized, and validated before being granted access to the resources required per tasks at the micro segmented network layers.

Guiding Principles of Zero Trust Security

Guiding Pillars of Zero Trust Security
Verify Explicitly

Authenticate and authorize only after a thorough verification of user and endpoints.

Limit User Access

Limit user access to provide just enough access for just enough time

Assume Breach

Assume Breach is a paradigm to treat that a breach has already occurred, and accounts have been compromised.

Features of Network Access Control with Zero Trust Network Access (ZTNA)

Today, there has been an exponential shift from desk-based jobs to a work culture that suit individuals to work from anywhere. With employees working remotely and the demand for IoT solutions rising at a peak, a new era of Cyber Security arises wherein security officers must be capable of managing Enterprise of Things and BYOD (bring your own devices) effectively. For this, the requisite of a secure network access control has not been more critical.  To combat this, the implementation of secure NAC is administered with Zero Trust Security.
